Question about Hayward H Series Millivolt 250,000 Btu Pool Heater H2501

Hayward H250 (millivolt) pilot won't stay lit

I can get the pilot to light and stay lit as long as I keep the gas control knob depressed. As soon as I let the control knob up the pilot goes out.

Any help appreciated!

Pilot light blew out by a fan..I turned the control off..How do I Ignite Please


First locate where to light pilot. You can do this by following thin aluminum colored tubing from control valve to inside heater.In general on top of your gas control valve is a knob. Turn indicator of this knob to pilot and depress knob. This will start gas flow to pilot at end of thin tube. Hold this knob in the depressed position and light pilot. DO NOT release knob for 30 -45 seconds. Then release knob and pilot will remain lit. Then turn knob to on position. If pilot will not stay lit you may need a new thermo coupler, which senses heat from flame to keep pilot gas flow open.
Good luck

How do i light the pilot light for the hayward


The lighting instructions are usually located inside the heater on the inside of the access panel or on the firewall near the gas valve.

Most millivolt heaters require you to turn the gas valve knob to the pilot light position and then depress the knob while lighting the pilot through the pilot hole. This varies depending on the exact model.

This is definately hands down a bad thermocouple. The thermocouple sits at the bottom of the burner tray. You will need to remove the nut secureing the pilot assembley and remove the wires.. I will post a link to the manual for this heater below so you can look at the parts diagram to find the thermocouple placement if neccessary. It will also have the part number so that you can order it.

Note: thermocouples can be generic and purchase at a local HVAC or pool/spa retailer.

Refer to page 28 for a diagram of what the pilot assembley looks like. The thermocouple is here in figure 46. Written Instructions for removal of the pilot assembley is on the bottom right of page 28 as well.

Unit dosn't seem to bve sensing flame. Clean your flame sensor. Its connected to your pilot light assembly usually. Its a metal rod that sits inside the flame. Could also be bad and need replaced. Hope this helps.
